CREST (Coupled Routing and Excess STorage), a high-resolution distributed Hydrological Model developed through a collaborative effort among OU, the ARRC and CEES, was adopted by the NASA Marshall Space Flight Center for their SERVIR-Africa and SERVIR-Mesoamerica system deployment. SERVIR, a joint NASA-USAID initiative, is a Regional Visualization and Monitoring System that currently provides critical and actionable information for Central America,the Dominican Republic and East Africa, and addresses the nine societal benefit areas of the Group on Earth Observations (GEO): disasters, ecosystems, biodiversity, weather, water, climate, health, agriculture, and energy.
